Format Commit Messages

This feature allows you to format the results of commit message linting. The `format` function takes an object with a `results` array and returns a formatted string that can be logged or displayed.

const { format } = require('@commitlint/format');
const results = [
  { valid: true, errors: [], warnings: [] },
  { valid: false, errors: [{ message: 'type may not be empty' }], warnings: [] }
];
const output = format({ results });
console.log(output);
